Advantages of selective etching of horn screen

Electronic products have gradually become household names. In the field of consumption, due to the fast iteration speed and short life cycle of electronic products, it has a very strong trend, requiring fast listing speed, diverse styles, miniaturization of samples, and precision tolerance within microns, the traditional manufacturing technology can not meet the current needs.

In electronic products, the handset net, loudspeaker net, earphone net, speaker net and other audio equipment are required to be dust-proof and beautiful. Therefore, etching has strong advantages, and the thickness of etching is between 0.01 and 2 mm, while stamping and laser processing can not meet the requirements of product processing with a thickness of less than 1MM, especially the earphone net, and the etching accuracy can reach +/-0.0075mm through the loudspeaker net. Batch production and processing can be realized. The commonly used trumpet nets have an etching aperture of more than 0.5mm, while mobile phone manufacturers need apertures of 0.3mm and 0.2 mm. These apertures are all micropores, which require high technology. The best choice for micropore technology processing is etching technology, and the aperture can reach 0.1mm, which can completely meet the aperture requirements of various trumpet nets.
